Of course not. The tools are not currently available (although for all we know, there may be professional coders using Swift Playgrounds for some of their work). My point is that absolutist statements about whether a platform is or is not viable can be transient in nature. The arguments here have almost entirely been about the lack of availability of a particular app. If the app becomes available, the argument is over.
An app is not an intrinsic property of a hardware platform. What matters in the end is whether the hardware is capable of running the app. There's a difference between "can't run on the platform" and "hasn't been written to run on the platform."
There have been several comments in this thread that certain apps shouldn't be used on laptops, as they don't have the power of desktops. Seriously? Now we're talking about speed of throughput, or the challenges of working on a smaller display, not the ability to run the code. One person's need for speed may be different than another's, but it doesn't mean one of those users is less professional than the other.
It's kind of like a Hasselblad photographer claiming a Nikon or Canon user is not professional, because his camera produces a larger negative. In the end, it's not the size of the negative, it's what's recorded on the negative that counts.
